To aZZ whom it may concern:

Be it known that I, ALFRED G. F. Kciiowsin, a citizen of the UnitedStates, residing in Brooklyn borough, in the ooun cy oi isings, city andState of New certain new York, have invemcd V and useful improvements inType-(Writing Machines, of which she iollowing is a specification.

, T his invention relates to typewriting ma.- cliines in which arelativeshifting movement is effected between the types anci the platen, e0enable either lower case or capital letters tobe Written, andperticularlyic those machines in which the platen rennilns stationarywhile the type-oars are shifted up and do wn.

- ment, whereby One of the main objects of the invention is to providean improved connection between the type-bars and the key levers w ichextend rcm'wardly under the type-bar seg- Lil-6 type-bars are permit-tedto shift up and down while remaining con- 1 .nectecl to the levers.

I provide between inc type-burs which we mounted upon a sli-iitingsegment, and the key-opemlcd oell cranks, which are mounted upon theframework of the me.

chine, a series of individual slides, which have pin-aml-slotconnections to the typebars, for the usual purgiose' 1: 11d which alsohave pin-a11 l-slot connections to the bell cranks to permit relativeplay of these members during the prin'eing strokes, and also to permitup-and-down shifting of the tynebar segment for printing capital andlower case letters.

In another case, Serial l lo. 376,008, filed June 27, 1913),- n divisionof the present 0 e, 1 have claimed the means whereby the typebzirsegment may be shifted.

Another object is to improve the means for shifting and guiding thetype-bur segment.

Other features and advantages will. hereinafter appear.

Fig. '3 is a fragment of one of the slotted portions cf thetype roclaslmft 16 which er-:i nis chine lJGRK-tililll There are iuo oithe our "1 l 1g. tseici rocn shaft in (31'1 es arms 18 114:- opcosiceside sand allliS sh en eni-"ling from le Fig. 3 than: the opposite endoi n.

also terminates in a dead or dwell portion gage upper and lower stops 2728, secured upon each of the legs 20, to arrest the segment when shiftedin either directibn. The

lugs 26 have vertical slots 26 engaged by.

screws 26*, which adjustably fasten the lugs to the legs, the adjustmentbeing determined by the throw of the slotted arms 18.

The segment is guided by pairs of rolls 29, each pair-comprising anupper and a lower roll journaled to a vertical carriage 30 and occupyingvertical grooves 31, 32, the grooves 31 formed in the outer sides of thelegs 20, and the grooves 32 formed in the inner sides of'a pair ofplates 33 secured upon the opposite sides of the framework. Eachgroovehas converging or V walls 34, Fig. 8, and the ends of the rollsare coned to fit these converging walls.

The plate 33 is, adjustable toward the leg 20 at Figs. 8 and 9, toadjust it to the rolls, and take up play. The plate has a verticaltongue 35'to fit in a groove 36' in a part 37 of the framework of thetypewriter. By

- means of upper and lower screws 38 and intermediate screws 39, theplate 33 may be adjusted toward the left at Fig. 9 to tighten the rolls29, the latter having clearance at their ends, as shown at Fig. 8, toinsure that they will always fit. The screws 38 are threaded into thefixture 37 and bear against the tongue 35, and the screws 39,

Cit

which are threaded into the tongue may be tightened, drawing the tonguefirmly against the tips of the screws 38. Each car: riage 30, to whichthe rolls are journaled by pintles 40, has a lug 411, at its upper end,to catch upon the top of the plate 33, to sup port the carriage innormal position.

Upon the shaft 16 is a coiled spring 42. which partly counterbalancesthe weight of the segment and type-bars; the latter returning by gravityto normal position. A re-- turning spring 43 is connected. to one of thearms 18.

The type operating keys are designated as 44, and are mounted uponlevers 45 somewhat similar in form to the levers 12,

and fulcru med on the same bar 46, and having similar returning springs47. Upon the levers 4-5 are wrists 48 to engage slots 49 in thehorizontal arms 50 of a set of bell cranks, the latter also comprisingupright arms 51 having wrists 59 to engage slots 53 extending up anddown in arms 54 provided upon slides55, the latter having wrists 56 toengage slots 57 in the type bars 1, to swing them upto print, (Fig. 1).

The slot 53 extend up and down in the direction in which the type barsegment is shifted, and is longenough to accommodate i such shiftingmovement, so that the station- I ary bell cranks 51 remain connected tothe type bars when they are elevated to print capital letters as at Fig.3.

The bell cranks are indicated diagram matieally in front elevation atFig. 4, and it will be seen that between their ends nearly all of thebell cranks, have inward bends 58,

Fig. 4, to bring the upper ends of the bell cranks into proximityto'their respective op-L crating slides thearms 54 in said slides,

or actuators being preferably all vertical (front view in Fig. to agreewith the vertical shifting of the segment, andthe tops of the bellcranksalsostanding vertlcally at said Fig. 4. It will also be seen at. 1

said figure, that the slides 55 are placed ra-- dially, and that thearms 54 are bent at corresponding angles to the bodies of the sl des tobring the arms to vertical positions. The

in the radial type-bar slots 3, and lie side by side with the portionsof the slots, as at F 1g. 4; said slots therefore serving to guide theslides At Fig. 2, is seen a conformation of the lower portion ofthesegment 4 and a manner of mounting therein the type-bar fulcrum rod 2,as well as the front and rear curved rods 60, 61, upon which the slides55 are guided.;-all ofsaid rods being'insertedin curvedslots'in thesegment, the inner ends of the slots being enlarged to fit the rods, andretain them in place. The typebar operating slides 55 are provided withslots 62, 63,;wvhereby they slide upon said guide rods 60,61; and theseslots are preferably formed on a curve, as illustrated at Fig. 1, whichis nearly concentric with the fulcrum (i l ofthe bell crank 51. This isl done to give the slide a curvilinear motion, so that the wrist 56thereon will have the desired action uponthe connected type bar;

the direction of the movement of the wrist 06 being first along the slot57, so that the I type-bar is started slowly into motion, and

then transversely of the slot, so that the type-bar is speeded as itapproaches the platen.
